Costed Bill of materials report missing components

When running the Costed Bill of Materials Report some items will print displaying all components. Others do not. Bills are all setup as Standard.

BOM Options: Maximum number of levels is 10, but these are not levels, just components listed in the lines of the BOM. All have quantity and cost. Costing of the items are set to Standard in Inventory Maintenance and reporting inventory cost type parameters is set to Standard.

Have rebuilt BOM sorts but that didn't make a difference.

Sage 100 Premium 2018 with DSD Scanforce MB.

Not sure why some BOMs would print all component lines and others not.

Thank you for your assistance.
